I don’t use Google translate at home (I do in my RV but it’s stored), however my HomePods using the Home Assistant cloud TTS do not work under the Apple TV integration but they work fine with my primary TTS system, which is Airfoil that uses Airplay to each speaker. The problem appears to be the Apple TV integration as I can see my HomePods now show as “off” and won’t turn on.
For me, I turn off auto updating on HomePods (I have quite a few) until I test it, then I’ll download them all manually. There have been a couple updates that have thrown me into a tailspin. Fortunately I only updated one speaker today, but since I do this through Airfoil anyway I probably could but will wait for the Apple TV update to come, which I bet will soon.
Reloading the speaker under Apple TV doesn’t fix it either.
Update: re-adding into the HA worked. You don’t need to reset your homepod and re-add it to the Homekit. Just remove it from the HA and re-add again. Worked for me.
However. After finishing tts sentence, the home pod status remains as “playing”, instead of idle or else. Is there a way to fix it?
Sending “pause” doesn’t work for my case.
